Approximately Macroscopically Unique States and Quantum Mechanics
Huaxin Lin, Hang Wang
We show that Mumford's Approximately Macroscopically Unique (AMU) states exist for quantum systems consisting of unbounded self-adjoint operators when the commutators are small. In…

Almost commuting self-adjoint operators and measurements
Huaxin Lin
We study the problem when an almost commuting -tuple self-adjoint operators in an infinite dimensional separable Hilbert space is close to an -tuple of commuting self-adj…
